Concrete History - Popuch Concrete Contracting, Inc.

Concrete History. Cement has been around for at least 12 million years. When the earth itself was undergoing intense geologic changes natural, cement was being created. It was this natural cement that humans first put to use. Eventually, they discovered how to make cement from other materials.

US4031183A - Process for calcining line - Google Patents

The processes range from burning heaps of line to use of intermittent and continuous vertical kilns; horizontal rotary kilns; flu-solids kilns; and circular refractory hearths; many of which have been adapted for operation with fuels as diverse as wood, oil, coal, coke or natural gas depending upon local costs and.

Vertical axis wind turbine - Wikipedia

A vertical axis wind turbine has its axis perpendicular to the wind streamlines and vertical to the ground. A more general term that includes this option is "transverse axis wind turbine" or "cross-flow wind turbine." For example, the original Darrieus patent, US Patent 1835018, includes both options. Drag-type VAWTs such as.
